Almost everyone today has his or her mobile phone and Bluetooth has already become a standard inclusion on most mobile phones, laptops and PDAs. Data transfer through Bluetooth among the handheld devices is common and popular. Bluetooth establishes links in a more convenient manner to facilitate sharing data between devices. It motivates us to apply this technology to hypermarket advertising. In this paper, we present a framework that pushes advertisements to hypermarket customers with handheld devices via Bluetooth. We have implemented the system and completed the field test in a local superstore. The result was satisfied. Hypermarket can reduce the cost of distributing handbills by using this proactive advertising system which also provides dynamic delivering of advertisement. In other words, hypermarket can make and deliver advertisement on the fly without resort to printing it.
